A modular catalyst bed support can be used to increase the number of catalyst beds available in a reactor. The modular catalyst bed support can include a lattice with a plurality of lattice openings and modules inserted into the lattice openings. The modular catalyst bed support can rest on top of an underlying catalyst bed, which can reduce or eliminate the need for attachment of the modular catalyst bed support to the walls of the reactor.

A circulating fluid bed reactor such as that used in fluid coking processes has a circular dense bed reaction section above the reactor base where the fluidizing gas is injected and a plurality of frusto-conical baffles in the dense bed reaction section, each of which depends downwardly and radially inwards from the reactor wall to a lower, inner edge defining a central aperture. The baffles are preferably provided with downcomers which permit downward flow of solids and upward flow of gas through the baffles.
